Problems solved by technology

[0002] With the development of electronic technology, people have higher and higher requirements for signal integrity. From DDR2 to DDR3, to today's DDR4, from PCI to PCIE, the signal function is continuously strengthened, and the complexity of the circuit board follows. The correct connection of numerous and intricate signal lines will increase the workload of many engineers than before
Layering signal lines can properly simplify the complexity of signal lines, but the current Candence software can only display flying lines, but cannot layer them, and manual layering is often error-prone and wastes a lot of time

Embodiment Construction

[0014] A method for automatic layering of flying lines based on Allegro, PCB wiring through Allegro software, using the skill program of the Allegro software interface and forming automatic layering of flying lines according to the skill program: configure allegro.men in the menu bar of Allegro software The preset path of the file, add the corresponding command item to form the automatic layering of the flying line in the toolbar item, add the command code for forming the automatic layering of the flying line to the allegro.ilinit file under the skill file path, and it will form The flying line automatic layering file is placed under the skill file path to complete the command of forming the flying line automatic layering in the menu bar.

[0015] According to the above method and content of the invention, the present invention will be further described in conjunction with the accompanying drawings.

[0016] The invention provides an Allegro-based flying line automatic layerin...

Abstract

The invention discloses an Allegro based fly line automatic layering method, and belongs to the technical field of computer application. An editing operation is performed on a database by using an expanding Skill interface provided by Allegro software; layering is preformed according to differences of circuit board signal lines and the importance thereof; wire layout is performed according to the demands of actual circuit boards, and line crossing and line stacking can be avoided; line connection is performed with the layering manner as a reference, and then functions which are not provided by the program can be achieved, the efficiency of Layout work can be improved, and the line stacking due to too many fly lines can be effectively solved; a plan of an engineer is facilitated before line layout; and the time is saved, the working efficiency can be improved, and unnecessary repeated works can be reduced.

Description

technical field [0001] The invention discloses an Allegro-based method for automatic layering of flying wires, which belongs to the technical field of computer applications. Background technique [0002] With the development of electronic technology, people have higher and higher requirements for signal integrity. From DDR2 to DDR3, to today's DDR4, from PCI to PCIE, the signal function is continuously strengthened, and the complexity of the circuit board follows. The correct connection of numerous and intricate signal lines will increase the workload of many engineers more than ever. Layering signal lines can properly simplify the complexity of signal lines, but the current Candence software can only display flying lines, but cannot layer them, and manual layering is often error-prone and wastes a lot of time. Allegro is a PCB design routing tool. Allegro provides a good and interactive working interface, combined with Cadence, it can provide complex PCB design routing so...
